VPSA oxygen generator equipment uses air as raw material under normal temperature and low pressure, and separates the oxygen (about 21%) in the air directly by physical methods, thereby producing high-purity medical oxygen with a concentration of 90%- 96%. VPSA oxygen generator is characterized by fast oxygen production, safety, economy, and convenience, and can easily replace the bottled oxygen and chemical oxygen production in the past.

When the VPSA oxygen generator equipment produces oxygen, the molecular sieve discharges the adsorbed nitrogen back into the ambient air during decompression, and can adsorb nitrogen and produce oxygen during the next pressurization. The whole process is a periodic dynamic cycle process. Molecular sieves are not consumed. Therefore, compared to other equipment, it is more energy-saving and environmentally friendly.

In recent years, VPSA oxygen concentrators have gradually been promoted and applied in large and medium-sized hospitals in China. VPSA oxygen concentrators have the function of health care. By supplying oxygen to improve the oxygen supply of the body, it can achieve the purpose of oxygen supplement and health care. Suitable for middle-aged and elderly people, people with poor physical fitness, pregnant women, college entrance examination students and other people with varying degrees of hypoxia. It can also be used to eliminate fatigue and restore physical functions after heavy physical or mental exhaustion.
